MDS PREP
Stippling is seen on
1) Marginal gingiva
2) Attached gingiva
3) Interdental gingiva
4) None of the above
Periodontics
Answer: 2
Stippling is typically observed on the attached gingiva, indicating healthy
tissue.
An acute periapical abscess can be differentiated from an acute periodontal abscess most reliably by the
1. degree of tooth mobility
2. nature of the swelling
3. blood and urine examination
4. response to periodontal probing
Periodontics
Answer: 4
The response to periodontal probing is a reliable method to differentiate
between an acute periapical abscess and an acute periodontal abscess. An acute
periapical abscess typically does not show significant probing depth changes,
while a periodontal abscess may show increased probing depths due to periodontal
tissue involvement.
The treatment of choice for generalized fibrous gingival hyperplasia is
1. lateral pedicle flap
2. full thickness flap surgery
3. gingivectomy
4. root planning and curettage
Periodontics
Answer: 3
Fibrous gingival hyperplasia, also known as gingival overgrowth, is
characterized by an increase in the size of the gingival tissue due to an
excessive accumulation of collagen and other extracellular matrix components.
This condition can be caused by various factors, including certain medications
(like anticonvulsants, calcium channel blockers, and immunosuppressants),
hormonal changes, or chronic inflammation.
Lower first molar has furcation involvement with bifurcation caries, treatment of choice is
1. Endodontic treatment followed by hemisection
2. Hemisection followed by endodontic therapy
3. Apical curettage only
4. None of the above
Periodontics
Answer: 1
The treatment of choice for a lower first molar with furcation involvement and bifurcation caries is endodontic treatment followed by hemisection.
Laboratory test of ANUG is
1. Complement fixation
2. Dark field examination
3. Tissue culture
4. Animal inoculation
Periodontics
Answer: 2
Laboratory tests for ANUG typically involve dark field examination.
Least involved furcation is
1. Mandibular first molar
2. Maxillary first molar
3. Maxillary first premolar
4. Mandibular second molar
Periodontics
Answer: 3
The least involved furcation is seen in the maxillary first premolar.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
Site specific characteristic in oral cavity is not seen in which disease
1. Herpetic gingivostomatitis
2. ANUG
3. Diphtheria
4. Desquamative gingivitis
Periodontics
Answer: 1
Site-specific characteristics are not seen in herpetic gingivostomatitis.
